                           int b)
o pow_long 
 public static long pow_long(long a,
                             long b)
o closeInputStream 
 public static void closeInputStream(InputStream ss)
o closeOutputStream 
 public static void closeOutputStream(OutputStream ss)
o closeSocket 
 public static void closeSocket(Socket ss)
o bytescat 
 public static byte[] bytescat(byte b1[],
                               byte b2[])
Appends b2 to b1 and returns the result.

o bytescut 
 public static byte[] bytescut(int i1,
                               int i2,
                               byte b[])
Cuts between i1 and i2 in b (inclusive) and returns the result. Assuming i1
o bytes2int 
 public static int bytes2int(byte data[])
Creates a integer out of four bytes using the big endian technique

o int2bytes 
 public static byte[] int2bytes(int data)
Returns a four bytes array representation of a integer using big endian technique.

o getDigit 
 public static int getDigit(int position,
                            long value)
Returns the named digit from a long starting with digit 0 at the rightmost position. No parameter checkings are done. If some error detected then return is zero !!!

o stringWidth 
 public static int stringWidth(String str,
                               FontMetrics fm)
Returns the pixel width of the specified string using the specified fontmetric.

Returns:
0 in case of error, pozitive otherwise
